Inconel 600 Pipe Fittings
Inconel 600 Pipe Fittings ( UNS N06600 )
Inconel 600 Pipe Fittings are manufactured from a premium nickel-chromium alloy known for its exceptional resistance to heat, oxidation, corrosion, and stress cracking. Inconel 600 (UNS N06600) combines excellent high-temperature strength with outstanding chemical stability, making it ideal for demanding applications such as power generation, chemical processing, nuclear plants, and aerospace systems.
These fittings exhibit excellent resistance to chloride-ion stress-corrosion cracking, sulfur compounds, and oxidizing environments. With superior hot- and cold-workability, Inconel 600 Pipe Fittings provide long-lasting reliability in extreme conditions, maintaining structural integrity at temperatures up to 2150°F (1176°C). They offer easy fabrication, weldability, and durability across a wide range of temperatures and corrosive atmospheres.
